ELECTRIC-Ll SPECIFICATION forming part of Letters GHT SHADE.

Patent No. 432,826, dated July 22, 1890.

Application filed November 14, 1889- Serial No. 330,362. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. GoEHsr, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement-in Electric-Light Shades,of which the following is a specification.

The objects of my invention are to provide a simple and economicalconstruction of shade which can be readily applied to an electric light;to avoid the necessity of providing an electric-light socket withspecial means for holding the shade thereon, and to provide certainimproved matters of detail, as hereinafter described.

In an electric'light shade characterized by my inventionI provide theshade with an upturned collar which is adapted for engaging anelectric-light socket, and which is clamped upon t-he-shadethat is tosay, connected with the shade by a clamp-joint. The collar can be simplyan annular metal band, but it is preferably provided with spring-fingersso as to avoid the necessity of a ring-nut on the socket for holding theshade in connection Other matters are hereinafter more particularlydescribed.

In the accompanying drawings, Figure 1 represents in side elevation ashade provided with my invention and applied to the socket of anelectric incandescent light. Fig. 2 shows the shade in vertical centralsection and the electric-light socket in elevation. Fig. 3 is a likesection through the shade, but shows the shade composed of two parts,whereof one constitutes a holder for the other. Fig. 4 represents, on aslightly larger scale, the collar prior to its application to the shade.

In said drawings, A indicates the shade, and B denotes a collar whichrises from the central portion of the top of the shade. The top orcentral portion of the shade is provided with a circular opening intowhich the lower end of the collar Bis fitted, and asecure union betweenthe shade and the collar attained by clamping the collar uponthe edgeportion of the shade, which immediately surrounds the saidcentrally-arranged top opening of the latter. In order to thus clamp thecollar upon the shade, the collar is provided with anexternally-arranged annular bead Z), which is formed a short distanceabove its lower edge, as best illustrated in Fig. 4-, and in applyingthe collar thus formed its lower end portion 1) is fitted within thecentral top opening of the shade, so that the head I) will rest upon thetop of the shade, and said lower end portion of the collar is then bentout-- wardly and upwardly against the under side of the shade, whichwill be clamped between the bead b and the bent end portion 1) of thecollar. This can be performed by suitable dies in one operation, andhence involves a normnal cost.

For the broader purpose of my invention the collar may consist of anannular metal band; but as afurther improvement I provide it withspring-fingers b arranged to clasp the socket C of an electric light, asin Figs. land 2. I also prefer adapting the spring-fingers of the collarto engage a bead c on the socket O by bending or grooving said fingersas at b Z2 in which way the shade will be securely held upon the socketand all danger of slip on the part of the shade avoided.

While for certain purposes the shade could be made wholly or partiallyof paper, or of various materials other than metal, I prefer forming itof metal so that the shade can be struck up in one piece, as in myapplication of even date herewith. The shade mayflare from the line ofits unison with the collar B, or it may have a fiat annular top portiona, which is surrounded by the flaring portion a. lVhile the shade may bemade in either of said ways, I find the provision of the fiat centralportion a preferable. This central portion amay be of any desired width.If desired, the flaring portion a can be made separate from the centralportion a, and removably connected therewith in any suitable waythus,for example, in Fig. 8 the central portion a is provided with aset-screw D and adapted to serve as a holder for the shade portion a.

What I claim as my invention is- 1; An electric-light shade constructedwith the annular flat central portion a, a surrounding flaring portion,and a centrally-arranged upturned collar B, provided withspring-fingersarranged for engaging an electric-light socket, the innerannular edge of the centrally-arranged flat portion of the shade beingclamped between a head on the collar and the outwardly-bent lower end ofsaid collar, substantially as set forth.

2. A11 electric-light shade having an opening, a collar B, securedwithin said opening and provided with spring fingers having bends orgrooves 12 therein, adapted to engage the bead on an electric-lightsocket, substantially as described.

3. The combination, with an electric-light socket, of a shade comprisinga flat central portion a and a surrounding flaring portion a, said flatportion having a central opening,

I a collar B, having spring-fingers for clasping the socket, the lowerend portion of said collar fitting Within said central openingin saidflat portion a and having a bead resting against the top thereof, and anoutwardlybent lower end portion 1), which is bent to fit against theunder side thereof, substantially as set forth.
